The present application is based on and claims the benefit of U.S. provisional patent application Ser. No. 60/861,372, filed Nov. 28, 2006; and this application is a Continuation-in-Part of U.S. patent application Ser. No. 11/024,510, entitled “ODOR ABSORBING SYSTEM AND METHOD,” filed Dec. 29, 2004. The contents of the above-identified applications are hereby incorporated by reference in their entirety.

FIELD OF THE INVENTION

The present invention generally relates to an odor absorbing system configured to reduce odor emanation from a person into an environment surrounding the person and, more particularly, to an odor absorbing system that maintains its odor absorbing capabilities during periods of nonuse.

BACKGROUND OF THE INVENTION

Outdoorsmen and women, particularly hunters, often take steps to prevent their detection by wildlife. Such steps include making themselves less visibly detectable to wildlife by, for example, hiding in a tree-stand or wearing camouflaging clothing.

Such wildlife detection preventing methods also include reducing the likelihood of being detected by scent. For example, animals positioned downwind of the person can easily smell bodily odors including natural body secretions. Other bodily odors that are detectable by animals include odors resulting from soaps, perfumes, shampoos, deodorants and other products that are applied to the body. Other strong animal-detectable odors include those embedded in our clothes that are acquired from the environment, such as cigarette smoke, odors from a cleaning detergent or fabric softener applied to the clothes when washed, and other odors.

Articles of clothing have been developed to prevent odor emanation from the person wearing the article of clothing. Examples of such articles of clothing are described in U.S. Pat. Nos. 5,383,236, 5,539,930, 5,790,987, 6,009,559 and 6,134,718 (hereinafter “Sesselmann patents”). Briefly, the patents describe articles of clothing that are formed of a base layer on which a scent absorbing means is “provided” by bonding a scent absorbing agent to a surface of the base layer through a silk-screen printing process.

The rate at which the odor absorbing materials (e.g., activated carbon and/or charcoal) absorb odors decreases with exposure to odors to a point where are no longer useful for scent absorbing purposes. Further, exposure of the odor absorbing materials to odors can take place from the moment the odor absorbing material is formed. As a result, the scent absorbing capability of the odor absorbing material decreases not only during use (i.e., while being worn), but also during periods of non-use, such as during manufacture of the product, transportation of the product, and while the product is being stored.

Further, these problems have been exasperated by the erroneous belief that some odor absorbing materials, such as those using activated carbon, have odor absorbing properties that can be renewed by washing and drying the material. For example, the Sesselmann patents incorrectly claim that when the scent absorbing means is activated charcoal, it may be reactivated merely by machine washing and drying the article of clothing. Instead, reactivation of activated charcoal requires a much more complicated process that cannot be performed by washing or drying machines. The one traditional way to “reactivate” activated charcoal is through a process called pyrolysis in which the activated charcoal is heated to over 1400° F. (800° C.) in a controlled atmosphere of low oxygen. Accordingly, the useful scent absorbing lifespan of the activated charcoal is limited and basically non-renewable to the average consumer. As a result, the entire scent absorbing clothing described in the Sesselmann patents must periodically be replaced in order to maintain the desired scent absorbing performance.

One result of this erroneous belief that some odor absorbing material can be renewed is that odor absorbing materials, and clothes formed of the odor absorbing materials, have been shipped from manufacturing plants to distributors/retailers and stored in packaging that exposes the odor absorbing material to odors. Additionally, the clothes with the odor absorbing material have been exposed to odors in retail stores where they are simply hung on hangers without taking steps to seal the clothes and the odor absorbing materials in an airtight or substantially airtight container. Further, once purchased by the consumer, the odor absorbing materials continue to absorb odors during transport and during periods of non-use (i.e., storage). The instructions for clothes containing odor absorbing materials, particularly those using activated carbon, have indicated that limiting exposure of the product from odors is unnecessary because the odor absorbing capability of the odor absorbing material in the clothes can be renewed or reactivated by washing the clothes and drying them in a dryer.

Further, the odor absorbing capabilities and lifespan of the odor absorbing materials, and clothes comprising the odor absorbing materials, is often unknown to consumers of the products. For instance, a prospective purchaser of odor absorbing clothing products does not know the quantity nor the amount of time that the product has been exposed to odors since the product was manufactured. Thus, consumers are forced to make purchasing decision without knowing the odor absorbing lifespan and properties of the odor absorbing material and product.

Unless the odor absorbing material is protected from exposure to air and odors, its odor absorbing capability will begin to diminish immediately after it is formed. Therefore, a continuing need exists for ways to provide and store odor absorbing materials and clothes comprising odor absorbing materials to prevent undesired odor absorption during periods of transport, storage, and other non-use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the invention are based on a recognition that odor absorbing materials have a limited useful odor absorbing life span. As discussed above, exposure of the odor absorbing material to odors can take place from the moment the odor absorbing material is formed. Thus, unless the odor absorbing material is protected from exposure to air and odors, its odor absorbing capability will begin to diminish immediately after it is formed.

System and Method of Reducing Odor Emanation from a Person

One embodiment of the invention relates to an odor absorbing hunting system 100, illustrated in FIG. 1, that comprises an article of clothing 102 for hunting, a container 104 having a substantially airtight interior chamber 106, and an odor absorbing material 108 stored in the interior chamber 106 of the container 104. The odor absorbing material 108, which is also illustrated in phantom with the article of clothing 102, is configured for use with the article of clothing 102 to absorb odors emanating from a person wearing the article of clothing 102. Embodiments of the article of clothing for hunting (hereinafter “clothing”), the container and the odor absorbing material will be described below. Embodiments of the invention include the various possible combinations of the embodiments of these elements.

FIG. 2 illustrates one embodiment of a method for reducing odor emanation from a person into an environment surrounding the person using the system 100. The method 200 includes a step 202 wherein an odor absorbing material 108 is provided. The odor absorbing material 108 is stored in an interior chamber 106 of a substantially airtight container 104 at step 204. Next, at step 206, the odor absorbing material 108 is removed from the container 104. Finally, the odor absorbing material 108 is worn at step 208. In one embodiment, the odor absorbing material is worn during hunting of wild game. Embodiments of the method in relation to the various embodiments of the system will be described below.

Embodiments of the Odor Absorbing Material

The odor absorbing material 108 of the system 100 is generally configured for use with the clothing 102, which is worn by a person, or for placement next to the person. The odor absorbing material 108 operates to absorb or adsorb odors emanating from the person wearing the clothing 102 to thereby prevent the odors from entering the environment surrounding the person. Herein, the term “absorb” is used to describe both absorbing and adsorbing functions.

FIG. 3A illustrates one embodiment of the odor absorbing material 108, that includes a base layer of material 301, which allows an airflow 302 to pass through the material 108. In one embodiment, the base layer 301 is formed of a breathable (e.g., porous) material that allows air to pass through the material 108 without substantial obstruction. Exemplary embodiments of the base layer 301 include mesh, cotton, polypropylene, wool, polyester, or other porous or fibrous fabric or material. The odor absorbing material 108 also includes an odor absorbing agent that is adapted to absorb at least a portion of the odors in the airflow 302 passing through the material 108.

In accordance with one embodiment, the odor absorbing agent 304 is bonded to a surface of the base layer 301, as illustrated in FIG. 3B.

In another embodiment illustrated in FIG. 3C, the base layer 301 of the odor absorbing material 108 comprises a porous material such at those described above. Additionally, base layer 301 may be formed of a fibrous material having a plurality of fibers 306 (shown in the enlarged cross section 305). The fibers may be woven or non-woven. In one embodiment, the odor absorbing agent 304, as illustrated, comprises a plurality of particles embedded within or on the fibers 306.

One embodiment of the odor absorbing agent 304 includes activated carbon or charcoal. In alternative embodiments, the odor absorbing agent can be formed of other known odor absorbing materials, such as chlorophyll, baking soda, activated alumni, soda, lime, zeolite, calcium, oxide, potassium, permanganate, and cyclodextrin.

Embodiments of the Container

The container 104 of the system 100 is generally configured to store the odor absorbing material 108 in an interior chamber 106 of the container enabling the odor absorbing material 108 to maintain its odor absorbing properties over longer periods of time as compared to prior art articles of clothing that are generally continuously exposed to environmental odors (even when stored during periods of nonuse). Thus, embodiments of the container 104 of the system 100 can extend the useful odor absorbing lifespan of the odor absorbing materials 108.

Some embodiments of the container 104 include sealed containers that can be resealed (e.g., containers with lids and resealable bags) and containers that are not configured to be resealed (e.g., sealed packaging that is torn to open). Further, the container 104 can be made of any suitable material such as plastics, metals, foils, and the like. Additionally, the materials used to form the container 104 can be rigid or semi-rigid, or malleable. In one embodiment, the material forming the container 104 includes materials that are significantly non-permeable (i.e., do not allow liquid or gases to pass through) and have a low odor production. In another embodiment, the container 104 can be formed of a clear material or a sufficiently transparent material as to allow one to see the contents of the container. In another embodiment, the material forming the container 104 is opaque to prevent or reduce the exposure of the odor absorbing material 108 or product formed of the odor absorbing material 108 to light.

In one embodiment, the container 104 comprises a sealable bag 400, as illustrated in FIG. 4. The interior chamber 106 of the container 104 is configured to store an odor absorbing material 108 or product comprising odor absorbing material 108. A seal 406 is configured to close an opening in the container 104 for accessing the interior chamber 106. When sealed, the container 104 substantially prevents odors present in an environment exterior to the container 104 from reaching, and being absorbed by, the odor absorbing material 108. In one embodiment, the seal 406 is reusable allowing the user of the system to place the odor absorbing material 108 in the interior chamber 106 and reseal the container 104 during periods of nonuse. Alternatively, the container 104 can be configured such that the seal 406 is not reusable (i.e., the container 104 is torn to open). Further, the container 104 can include a hanger 408 (for instance, an aperture) for hanging the container on a hook, clothing hanger, or the like.

Another embodiment of the container 104 is sized to receive the article of clothing 102, as illustrated in FIG. 5. The bag 500 is sized to accommodate embodiments of the article of clothing 102. In one embodiment, the bag 500 includes an integral hanger 506 on which the article of clothing 102 can be supported within an interior chamber 106 of the bag 500. The hanger 506 can include a hook, a loop, or any other means that extends into the interior chamber 106 of the bag 500. The hanger 506 is adapted to engage a hanger 504 on which the article of clothing 102 is hung. However, unlike conventional garment bags in which the hanger supporting the garment extends outside of the garment bag, this embodiment of a container 104 allows the garment 102 to be hung from within the interior chamber 106 of the bag 500 while maintaining the odor sealing capabilities of the bag 500.

In one embodiment, the bag 500 includes an integral hook 508 that allows the bag 500 to be attached to an object that is outside of the interior chamber 106, such as a bar. In one example, the hook or loop 508 that extends from the exterior of the bag is adapted to receive a separate hanger to facilitate hanging the bag on a clothes rack.

In one embodiment, the bag 500 includes a reinforced portion 510 configured to connect the hook 506 and/or the hanger 508 to the bag 500. In one example, the reinforced portion 510 has an enlarged surface area for distributing forces exerted by hangers 506 and 508 to a surface of the bag 500. In another embodiment, the hook 506 and the hanger 508 can be connected through an aperture formed in the container. In this manner, the reinforced portion 510 operates to seal the aperture to prevent odors from entering the interior chamber through the aperture.

In one embodiment, the bag 500 includes a seal 512 for accessing the interior chamber 106. The seal 512 can be configured to be reusable such that the bag 500 can be resealable. Alternatively, the bag 500 can be configured to be opened by tearing the bag 500 (i.e., seal 512 is not reusable). Examples of the seal 512 include conventional methods that facilitate the sealing and resealing the bag 500. For example, the seal 512 can comprise hook and loop fasteners (e.g., Velcro®, zippers, or other suitable fasteners). Alternatively, the seal 512 can comprises Ziploc® or other similar fasteners.

FIG. 6 illustrates one embodiment of the bag 500 including additional odor absorbing material 516 positioned within an interior chamber 106. The odor absorbers 516 comprise an odor absorbing agent such as those described above. The odor absorbers 516 can be integrated into the bag 500 or can be placed into pockets formed in the interior chamber 106 of the bag 500. The odor absorbers 516 are configured to absorb odors within the bag 500 thereby reducing remnant odors that may otherwise be absorbed by clothing hung within the bag 500.

Further, in some embodiments of the container 104 an inert gas is placed into the interior chamber 106 when the odor absorbing material 108, or products comprising the odor absorbing material 108, is stored therein. The inert gas is a gas having a low odor content. The inert gas discourages odors from being absorbed by the odor absorbing material 108 stored within the container 104.

Embodiments of the Article of Clothing

In one embodiment of the system 100, the article of clothing 102 comprises the odor absorbing material 108. In one embodiment, the article of clothing 102 comprises one or more different layers of material and the odor absorbing material 108 forms one of the layers, a portion of a layer, or a portion of the article of clothing. In another embodiment, the odor absorbing material 108 is adhered to a layer of the article of clothing 102. Examples of such articles of clothing are described in U.S. Pat. Nos. 5,383,236, 5,539,930, 5,790,987, 6,009,559 and 6,134,718. As discussed above, these patents incorrectly claim that when the odor absorbing means is activated charcoal, it may be reactivated merely by machine washing and drying the article of clothing. Embodiments of the present invention operate to maintain the odor absorbing capabilities of such articles of clothing. Further, embodiments of the article of clothing 102 comprise any articles of clothing used for hunting including hunting clothes, jackets, shirts, long underwear, pants, mittens, gloves, hats, sweatshirts, shorts, and other articles of clothing for hunting.

In one embodiment of the method 200, an article of clothing 102 comprising the odor absorbing material 108, such as the articles of clothing described above, is stored in the container 104. Further, the article of clothing 102 comprising the odor absorbing material 108 is removed from the container 104 and worn by a user. In one embodiment, the article of clothing 102 is worn hunting. In another embodiment, after use, the article of clothing 102 is removed by the user and placed in the container 104 for storage during non-use.

In one embodiment of the system 100, the odor absorbing material 108 is an odor absorbing insert configured for use with the article of clothing 102. In some embodiments, the article of clothing 102 is configured to be worn by a person and comprises a base layer including a vent. The base layer is adapted to substantially surround a portion of the person wearing the article of clothing 102. The insert includes a layer of breathable material and an odor absorbing agent on the layer of breathable material. The insert is configured for removable attachment to the article of clothing 102 adjacent the vent.

FIG. 7 illustrates one embodiment of the odor absorbing material 108 comprising an odor absorbing insert 700 including the odor absorbing material configured for use with embodiments of the article of clothing 102 having a base layer including at least one vent. The insert 700 includes a base layer 702 and an odor absorbing agent 704. Agent 704 can be bonded to or embedded in layer 702. Further, it is noted that insert 700 can be any size or shape to accommodate a specified application. Examples include, but are not limited to, inserts that are square, rectangular, circular, oval, triangular, or any other symmetric or asymmetric shape. In general, the odor absorbing insert 700 is removably attachable to the article of clothing 102, such as any articles of clothing used for hunting including hunting clothes, jackets, shirts, long underwear, pants, mittens, gloves, hats, sweatshirts, shorts, and other articles of clothing for hunting.

The insert 700 can be removably attached to the article of clothing 102 using any suitable means, such as Velcro® fasteners, zippers, buttons, etc., or stored within a pouch, pocket, or other compartment of the article of clothing. The insert 700 can be designed for removable attachment at any desired location of the article of clothing 102. In one embodiment, the insert 700 is removably attachable adjacent an opening in the clothing, such as a cuff, a neck line, a waist line, or other opening of the article of clothing where air that is exposed to the wearer can escape from under the article of clothing. In one embodiment, the insert 700 is removably attachable to the article of clothing 102 adjacent a vent in a base layer of the article of clothing.

FIGS. 8A-9B illustrate embodiments of the article of clothing 102 adapted to utilize an odor absorbing insert comprising the odor absorbing material 108.

In one embodiment illustrated in FIGS. 8A and 8B, the article of clothing 102 is configured to receive at least one odor absorbing insert 808 comprising the odor absorbing material 108. The odor absorbing insert 808 is, in one embodiment, similar to insert 700 illustrated in FIG. 7. However, the insert 808 can be any other suitable configuration. FIG. 8A is a partial front plan view of the article of clothing 102 and odor absorbing insert 808. FIG. 8B is a cross-sectional view of FIG. 8A taken generally along line 8B-8B.

The article of clothing 102, an exterior side 804 of which is shown in FIG. 8A, includes a base layer 806 that is configured to substantially surround a portion of the person wearing the article of clothing 102. In other words, the base layer 806 forms the body covering structure of the article of clothing 102. The at least one odor absorbing insert 808 is configured to cover at least one vent 810 in the base layer 806 of the article of clothing 102. The odor absorbing insert 808 is configured to absorb odors emanating from the person to prevent them from entering the environment surrounding the person.

Preferably, the odor absorbing inserts 808 and vents 810 are positioned on the article of clothing 102 such that, when the article of clothing 102 is worn by a person, they are likely to be positioned adjacent to primary odor-producing areas of the body. Examples of primary odor-producing areas include the armpits, the shoulders, the neck, the crotch area, and the mouth of the person.

Each vent 810 allows for an airflow 812 (outgoing airflow) to be directed through a specific location of the base layer 806 where the odor absorbing insert 808 is placed. As a result, outgoing airflows 812 are directed through the vent 810 and the odor absorbing insert 808 covering the vent 810 which absorbs odors in the airflow 812 to thereby reduce odor emanation from the person wearing the article of clothing 102 into the surrounding environment.

It should be understood that the term “vent”, as used herein, is intended to describe an opening through the base layer 806 whose purpose is to allow air to flow from inside the article of clothing 102 to the outside environment, when the article of clothing 102 is worn by a person. Thus, for example, when the article of clothing 102 is in the form of a jacket and is being worn by a person, the vent 810 within the base layer 806 allows the airflow 812 to pass between an interior side 814 of the base layer 806 that is closest to the person's body and the environment that is on the exterior side 804 of the base layer 806 that is opposite the interior side 814.

However, the vent 810 is distinguishable from a primary opening that is configured to accommodate a pass-through for a portion of the person wearing the article of clothing. For example, a primary opening at a neckline of an article of clothing in the form of a jacket is not a “vent” as the term is used herein since the opening at the neckline accommodates the neck of the person wearing the jacket. Similarly, a waistline of the jacket that is configured to accommodate a waist of the person wearing the jacket is not a “vent” as the term is used herein. Other examples of non-vent or primary openings in articles of clothing include the opening at a cuff of a sleeve of a shirt or jacket, a waistline of pants, and a cuff at the end of a pant leg.

The shape of the vents 810 of the article of clothing 102 can vary depending on their location. In accordance with one embodiment, the vents 810 include sides, generally designated as 816, that are displaced from each other when the base layer 806 is laid flat. In other words, in one embodiment, the vents 810 are formed by removing a portion of the base layer 806 rather than simply making a slit in the base layer 806. The vents 810 can be any desired shape including rectangular, circular, triangular, irregular, symmetrical, or other shape. In accordance with one embodiment, a breathable material (not shown), such as a mesh, spans the vent and is attached to the sides 816 of the base layer 806.

In general, the odor absorbing insert 808 is configured to cover the vent 810 in the base layer 806, as illustrated in FIGS. 8A and 8B. Although depicted as covering the interior side 814 (FIG. 8B) of the vent 810, the odor absorbing insert 808 could be positioned to cover the exterior side 804 of the vent 810 in the base layer 806.

The odor absorbing inserts 808 can be formed of any desirable shape and is sized to preferably cover the entire vent 810. In one embodiment, the odor absorbing insert 808 generally includes a layer of breathable material on which an odor absorbing agent is applied. For instance, in some embodiments the odor absorbing insert 808 comprises odor absorbing materials described in FIGS. 3A-3C. In one embodiment, the layer of breathable material includes a substantially porous material through which an airflow (such as airflow of FIG. 8B) can easily travel. Embodiments of the layer of breathable material include a mesh, cotton, polypropylene, wool, polyester, or other breathable fabric or material.

The odor absorbing agent is preferably bonded to one or more surfaces of the layer of breathable material in accordance with known methods. The odor absorbing agent 808 preferably includes activated carbon or charcoal. Alternatively, the odor absorbing agent can be formed of other known odor absorbing materials, such as the odor absorbing materials described above.

In accordance with one embodiment, the odor absorbing material 108 is configured for removable attachment to the base layer 806 of the article of clothing 102 at the vent 810. For instance, the odor absorbing insert 808 can be attached directly to the base layer 806 of the article of clothing 102 at the vent 810 as shown in FIG. 8B using one or more conventional fasteners 822. For example, a plurality of fasteners 822 can be provided each having one portion 824 attached to the odor absorbing insert 808, and another portion 826 attached to the base layer 806 of the article of clothing 102 at the perimeter of the vent 810. Examples of suitable fasteners include hook and loop fasteners (e.g., velcro®, buttons, zippers, or other suitable fasteners), which allow for the removal of the odor absorbing insert 808 without damaging the article of clothing 102.

In one embodiment illustrated in FIGS. 9A and 9B, an odor absorbing insert 908 comprising the odor absorbing material 108 is configured for use with the article of clothing 102. At least one breathable pocket 930 is positioned at one of the vents 910 of the article of clothing 102, as shown in FIGS. 9A and 9B. The breathable pockets 930 are used to removably attach the odor absorbing inserts 908 to the article of clothing 102. FIG. 9A is a front plan view of an interior side 914 of the article of clothing 102 and FIG. 9B is a cross-sectional view of FIG. 9A taken generally along line 9B-9B.

Each breathable pocket 930 is preferably attached to a portion (e.g., an inside surface 914) of the base layer 909 at one of the vents 910. An odor absorbing insert 908 is contained in an interior chamber 932 of the breathable pocket. The breathable pocket 930 generally includes first and second layers of breathable material 934 and 936, respectively. The breathable material is preferably highly breathable such that it provides little resistance to an airflow 912 traveling through the vent 910. Examples of suitable breathable materials for use in forming the first and second layers 934 and 936 includes a mesh, a screen, and other highly breathable materials.

In accordance with one embodiment of the invention, the breathable pocket 930 is permanently mounted to the base layer 906. For example, the first and second layers 934 and 936 can be permanently mounted to the base layer 906 by sewing or gluing them to the base layer 906.

In accordance with another embodiment, the breathable pocket 930 is removably mounted to the base layer 906. For example, one or both of the layers 934 or 936 are removably mounted to the base layer 906 using suitable fasteners at the perimeter of the breathable pocket 930 such as those described above. Preferably, the first and second layers 934 and 936 of the breathable pocket 930 are permanently connected to each other and the fasteners are used to attach only one of the breathable layers to the base layer 906 at the perimeter of the vent 910. In accordance with this embodiment of the invention, the odor absorbing insert 908 could be non-removably contained in the breathable pocket 930, which is removably attached to the base layer 906 of the article of clothing 102.

Another embodiment of the breathable pocket 930 includes an opening 938 (FIG. 9A) through which the interior chamber 932 defined by the first and second layers 934 and 936 is accessible. The opening 938 can preferably be closed using a suitable fastener, such as those described above.

Additionally, the odor absorbing insert 908 is preferably sized to lay flat within the interior chamber 932 and may be configured to have a shape that substantially conforms to the shape of the interior chamber 932. As a result, the odor absorbing insert 908 can be designed for specific breathable pockets 930 and can be provided with different odor absorbing properties that are tailored to the location of the corresponding breathable pocket 930.

Additionally, the interior chamber 932 of the breathable pocket 930 is preferably only slightly larger in area than the odor absorbing insert 908 when both are laid flat, in order to accommodate the odor absorbing insert 908. Additionally, the interior chamber 932 of the breathable pocket 930 is preferably only slightly larger in volume than the odor absorbing insert 908. As a result, one embodiment of the breathable pocket 930 provides a snug fit for the odor absorbing insert 908. Such a snug fit allows the odor absorbing insert 908 to be held up against the perimeter of the vent 910 to thereby force most of the airflow 912 traveling through the vent 910 to travel through the odor absorbing insert 908 rather than around it.

One embodiment of the article of clothing 102 of the system 100 includes an article of clothing, illustrated in FIG. 10, that is adapted for use with odor absorbing inserts comprising the odor absorbing material 108. Some embodiments of the odor absorbing inserts that can be utilized with the article of clothing 102 are disclosed with regard to FIGS. 7, 8A-8B, and 9A-9B.
